Terry and the QPR defender used to be close friends during their days together in the heart of England's defence.
That friendship was shattered forever when Terry was banned for four games and fined £220,000 for racially abusing Ferdinand's younger brother, former Rangers defender Anton.
But a potentially explosive showdown on the pitch won't happen now after Ferdinand was ruled out of tomorrow's clash through injury.
The pair have yet to meet on the pitch since the publication of Ferdinand's autobiography, '#2sides', in which he called Terry "the biggest idiot" and wrote that his family had yet to receive a direct apology following the 2011 incident
QPR manager Chris Ramsey said: "Rio has unfortunately got an injury, he's had a knock.
"It's a recurring injury. He's someone we miss immensely. We miss his leadership qualities on the pitch. Unfortunately, he won't be involved in the game.
"The subject of Terry brings up a lot of different emotions. It would be odd to think that there isn't going to be an extra feeling towards that situation."
Ramsey yesterday laughed off claims made by former Hoops boss Harry Redknapp that there were people at the club actively working against him.
Redknapp makes the accusation in an interview on the BBC's 'Football Focus' today.
But Ramsey insists he doesn't know what his former boss is talking about.
"I'm really, really pleased with how the players have applied themselves.
"The staff have been brilliant. Everybody around the ground has been upbeat since I came in. We are all singing off the same sheet."
Tomorrow represents the first time that Jose Mourinho will have taken a seat as a manager in the Loftus Road dugout.
Rookie Ramsey - in his 10th game in charge - says he is excited not intimidated by the prospect of facing the two-time Champions League winner.
He added: "You work as a coach throughout your career to be sat alongside these type of people and to pit your wits against them
"He's a coach, I'm a coach. He's a man, I'm a man.
"I think I'm good, he knows he's good. But you have to be confident in yourself."
